摘要： Motor cooling system for refrigeration machine wherein one condenser connected to a main stage of the compressor is used to satisfy the cooling requirements of the system and a second condenser connected to a subsequent higher pressure compressor stage is employed for heating a medium to satisfy heating requirements of the system. The motor cooling system contains a three-way selector valve which connects either condenser selectively to the motor housing in response to the pressure in one condenser exceeding the pressure in the other condenser to provide a sufficient liquid refrigerant to the motor for cooling motor components under all operating conditions. The selector valve comprises a horizontally extending tubular portion having an annular seat at each end of the portion and a vertically extending tubular portion attached thereon. An axially movable ball is arranged in a horizontal portion to open selectively either seat and close selectively the opposite seat in response to the refrigerant pressure acting on the ball.

摘要： A mixed phase pump for rapidly rotating cryogenic machinery is disclosed, preferably for installation to a superconducting generator rotor. The superconducting generator rotor includes an inner and outer rotor structure joined in a thermally insulated configuration not unlike that of a Dewar flask. The inner rotor contains a support cylinder for a refrigerant, typically helium, which when refrigerated to 3.5.degree. Kelvin at one half a standard atmosphere under the normal rapid rotation of the axially aligned support cylinder, classifies itself into a two-phase liquid gas system. The phases include an outer cylindrical helium pool and an axially inward gaseous core separated by a cylindrical gas-liquid interface. During normal operation of the rapidly revolving rotor, a pump removes the gas for recooling to a liquid state by receiving the gas in the vicinity of the axis of the rotor at an inlet. During abnormal operation including stator short-circuit and rapid rotational vibrational acceleration and deceleration of the rotor, the normal cylindrical interface between the cylindrical helium pool and the vapor core is destroyed. The vapor core in the vicinity of the pump inlet becomes multiphasic and the pump inlet can induct/ingest quantities of liquid. Accordingly, a pump with the liquid gas classification volume located outwardly from the gas inlet to the pump is disclosed. This liquid trap volume in the pump assures that the outward passage of gas only from the pump occurs. Stability of the two-phase gas-liquid system as well as the prevention of thermal stressing of torque-transmitting members of the high speed rotating rotor is prevented.
